Japanese Garden

Move through the employee passageway toward the electronic door leading to another hallway. The employee corridor is patrolled by a pair of Heavily Armed Cyborgs. Sneak past them or fight, it's your choice. Either way, proceed to the target area after taking that call from Monsoon.

Fuel Cell Plus 004

The Blade Mode box containing this upgrade is found on a red catwalk above the gardens entrance. Use the nearby rooftops to reach the steps leading up to the catwalk.

The area is not all that well-defended so get in there and round up the guards. Grab whatever freebies you can find then head toward the pagoda, where you can slice some watermelons beyond the shoji doors.

Endurance Plus 007

Check the right corner of the pagoda on the outside (the section facing the bridge where Sam quips "Nothing like a swordfight under the cherry blossoms.") to find the Blade Mode box with this upgrade.

Endurance Plus 008

Climb to the top of the pagoda where the finial is located (it's where Raiden earns the Menace to Society achievement in the main campaign) and eliminate the enemies. Among the hostiles is a Slider that zips by to drop off a Custom Cyborg. Use the Stinger (Homing Missile) to shoot down the Slider so that it drops this upgrade.

Moving forward to the waypoint, defeat the team of Cyborgs and Fenrirs to open a new exit. Continue through that one toward the next corridor.

VR Mission Computer 004

In the hallway just past the Japanese garden proper after the battle with the Cyborgs and Fenrirs. Proceed left instead of right at the intersection to find this mission terminal on the floor.

This is toughest of the five VR missions and involves a six-round battle ending with GRAD boss. You will definitely want a full stock of Repair Nanopastes for this. There is one on a crate near the waypoint so go pick it up, activate the mission terminal then quit to make the item respawn.

Data Storage 004

On the way to the objective marker just before stepping into the elevator lobby, look to the left to spot a panel on the wall next to a potted plant. Slice through the panel with Blade Mode.

Fight your way past several waves of Mastiffs and Cyborgs at the destination. Take the elevator up to another floor when the area is clear.
